LOCK.

Application filed August 6, 1919;` Serial No. 315,700.-

To all whom t mag/concern:

Be itv known that 1, DANIEL.S.GEISER, a citizen of` the United States,` residing at Waynesboro, in the county ofljlranklin and State of Pennsylvania, have invented certain new and useful Improvements in Locks, of which the'followin'g is a spec1fication.

The present invention relates more particularly to knob-operated locks havingV means whereby the bolt will be'V actuated uponthe turning of the knob, or by the sliding movement `ofat least a portion of the knob-spindle.

One of the primary objects is to provide a structure that is simple Vandpractica'l, together with means whereby the bolt can be effectively latched against movement and can also be locked so that it may. be released only byv a proper key.

ln the accompanying drawings Figure 1' is a longitudinal sectional view through the preferred embodiment of the invention.

Fig.' 2v is a longitudinal sectional View at ri ht angles to Fig; 1.

Figs. S `and 9 are detail views of different tumblers that may be employed.

'Similar reference numerals designate corresponding parts in all the figures of the drawings.

A. portion of a door is illustrated in Figs.

-1 and 3, and is designated 10, said door'having a circulabore 11 therein to receive the lock.

' The'said lock consists of a cylindrical'casing 12, within which is'located a reciprocatory-'bolt 13,. the outerend of' which'is beveled, as shown/at 14, and formed to Vengage in 'a suitable recessV or the socket ofl a holding plate ina manner well understood. This bolt is provided with areduced tailpiece 15, and has an elongated opening 16 therethrough, in which lisformed a holding shoulder 17. An elongated opening 18 also extends through the bolt at right angles to and intersects the opening 16. For the purpose of projecting the outer end 14 of the bolt, a coiled spring 19 is located in a socket lock.

20 formed in the outer portion of said bolt,

Y said spring bearing at one end against the inner end ofthe socket, and at its other end against a floating plunger 21 that extends into said socket. Y

A holding latch is provided, comprising a shaft 22 having an outer handle 23 and providedat its inner end with a rock arm 24. The free end of this arm is adapted to engage ina recessed seatl 25 formed in the rear end. of the plungery 21, and is also adapted to be moved to a position behind the shoulder 17.' The latch therefore performs a double function, lin that it can be movedto a position to hold the bolt against retraction and toa position where it constitutes a-n abutment for the spring 19.V

On opposite sides of the door' 10 are placed escutcheon plates 26 having inwardly extending nipples 27 that enter openings 28 formed in the barrel or casing 12 of the These plates also have outstanding sleevev portions 29 forming bearing elements for ythe inwardly extending Shanks 30 of knobs 31. The two knobs B1 are connected by a spindle composed of two sections 32 and 33. The section 32 is secured to the Vknobs 31 by pins 34 and 35, while the section 33 is free from'said knobs. These two'sections have abuttingat faces, the section 32 being longitudinally slidable 'on' the-section but said sections being together rotatable by reason of their abutting flat faces. The section 32- is provided with a shoulder 36 adaptedto abut vagainst one end of a bell crank lever 37 pivoted within the barrel as shown at 38, the other end of saidlever being adapted to engagea shoulder 39 formed within the bolt 13. The other spindle section'- 3S has outstanding cam portions 40 that bear against shoulders 41 formed on thel bolt;

With this construction therefore, if the bolt 13 is free to move, it will be evident that if the inner knob 30 is pushed toward the door, the section 32 will move longitudinallyV on'the section 33 and the shoulder 36 striking the bell crank 87, will cause the latter to swing, thereby engaging it-with the shoulder 39 of the bolt, and pushing ysaid bolt inwardly. On the other hand, if either knob is turned, it will turn the section 32 and consequently the section 83, thereby swinging the cam elements 40, which abutting against the shoulders 41, will cause the retraction of the bolt.

.- Locking means for't'he bolt is also profvided, which can be actuated by a key inserted from either side of the door. To this end, there is a key receiving member 42 rotatably mounted in the barrel at one side of the tail-piece l5, said member having a key q 1 receiving slot 43 normally alined with openings 44 formed in the opposite rear portions of the escutcheoiis. Pivotally mounted at 45, directly-behind the key receiving member 42, is a holding dog 46 adaptedto swing between a position behind the tail piece l of the bolt and a position that will permit the passage oi said tail piece alongside the dog. VPivoted on the dog 46 is a plurality of tiunblers 47, a common pivot pin 48 beingpreferably employed for all the said tumblers. vThese tumblers i are yieldingly held in predetermined positions by leaf springs 49 carried thereby and bearing against the dog. yThe tumblers are provided with upstanding finger portions 5,0 located in position to be engaged by a key placed in the slot 42'when said key is turned, andthe dog 46,'as illustrated more particularly in Fig. 6,

'isp-provided with a recess 5l to receive the key. )The opposite walls of the recess con- Y Vstitute bearings for portions of such key. A

stopI'Od 0i' pin 52 is located in rear of the rear ends'of the tumblers 47, and said tumblers have recesses 53 to receive the same.V

. As will beY evident, the tuniblers maybe constructed in a variety of ways, so that some are normally positioned with their recesses in line with the stop pin 52, while others are out 'of line, as illustrated in F ig. 2'.

With this construction, and with the bolt lock asillustrated in Fig. 2, it will be evi- Vdent-that if the proper key is introduced into the member 42, and turned, the said key will not affect those tumblers which have their recesses53 alined with the stop pin 52,

but. will swing those tumblers which haveV Y t ieir recessesout of alinement, soas to aline the same therewith, thereupon-the key will Vengage the dog 46 and Vswing the same until Y it is out of alinement with and the bolt will be freefor operation by the tail-piece l5 the knobs. It an improperly shaped key is introduced, however, it' may eitherfail to move the tumblers that are in locking position, or will move those that are Vout of lockl-a'rejin the same direction.
